What is the difference between series & parallel hookup?
A. Wiring batteries in series will result in double the voltage with the capacity of the smallest pack. Wiring batteries in parallel will result in douple the capacity at the voltage of one pack. Some important notes: Series: Do NOT wire packs of different capacities in series…one will die first and be reversed, possibly damaging the pack or even causing an explosion!! Additionally, be sure to use the same set of packs every time, so that they are all discharged and charged together to avoid cell reversing. Parallel: You can wire packs of differing capacities in parallel, though it is still best to use identical packs. You MUST use packs of the same voltage!!
